The Emerald Ash Borer, a beetle that’s infested ash populations in 15 states and two Canadian provinces, has for the first time been spotted in New York east of the Hudson River.

The beetle, an invasive species that came here from China, was found in Dutchess County. The spot was across the Hudson River from an infestation found two years ago in the city of Kingston, according to the state Department of Environmental Conservation.

Emerald Ash Borers, shiny green bugs small enough to fit on a dime, kill all North American ash species. In an effort to find the bugs before they do too much damage, the DEC and U.S. Forest Service strip away bark from sections of ash trees. This attracts the beetles if they are in the area.
